Description

Cover for post carrier, bottom sleeves and the like

The invention relates to a cover for fasteners of wooden structures, in particular for pole support and / or for ground sleeves. Furthermore, it relates to a fastening system for a wooden construction with such a cover.

Fasteners for wooden structures typically consist of galvanized iron flanges with holes through which a wooden structure can be fastened with nails or screws. In this case, the term "hollow construction" should be understood to mean any component made of wood, for example a board, beams, posts or the like. Typical examples of said fasteners are post carriers for screwing onto a level surface or for insertion into the ground, as described for example in DE 299 15 248 U1, or ground sleeves with a sleeve-shaped receptacle for round or square wooden beams and with means for attachment on or in the ground, as described for example in EP 657 604 B1.

The problem with the known fasteners for wooden structures is that exposed sharp edges, nail heads, screw ends, nuts and the like bring with it a risk of injury and act as mudflaps. Furthermore, the fasteners are often in the visible area, where they appear aesthetically disturbing.

Against this background, it was an object of the present invention to provide means for improved design of fastening systems for timber structures. This object is achieved by a cover with the features of claim 1 and by a fastening system having the features of claim 17. Advantageous embodiments are contained in the subclaims.

The solution according to the invention consists in a cover for fastening elements of wooden structures, for example for pole supports and / or ground sleeves of the type mentioned. The cover is characterized in that it has means for fixing to such a fastening element and / or to the associated wooden structure (for example a wooden beam). Furthermore, it should cover substantially all visible surfaces of the fastener when it is in its use state, d. H. is fixed to the fastener and / or on the wooden structure. Through the cover, the appearance of the fastener can be designed independently of the technical requirements. In particular, screw heads and the like can be covered and the device given an aesthetically pleasing surface design.

For the means for fixing the cover, there are many different ways to realize. Thus, the cover could be glued, screwed or connected by magnetic forces, for example, with the fastener or the wooden structure. Preferably, however, the cover has clamping means with which it can be clamped to the fastening element. Such an attachment in the press fit has the advantage that it can be performed without special tools, that it is ro bust against Maßvariationen, and that on the cover no externally visible changes (for example, screw holes) are necessary. Furthermore, a clamp fastening can generally be realized with very many forms of fastening elements, so that such a cover can also be provided in particular for retrofitting to existing post carriers, ground sleeves and the like.

According to a preferred embodiment, the clamping means have two opposing and at least in sections at an angle of inclination conically running to each other clamping surfaces, said sections may be formed on one or both clamping surfaces. By not exactly parallel, but at an angle of typically 0.3 ° to 5 ° inclined clamping surfaces, an object such as a flat iron corresponding width can be clamped by widening the clamping surfaces between them.

According to a development of the preceding embodiment, the clamping surfaces (preferably along one of their edges) have sections with different angles of inclination. This can accommodate the fact that an article to be clamped, such as a flat iron, is typically not the same width along its entire extent. The clamping fit takes place in these covers primarily on the more inclined portions of the clamping surface.

The fixation of the cover can also be achieved by locking means with which the cover can be fixed to the fastener in a locking seat. By definition, a "locking seat" connects two parts in a form-fitting manner, wherein the connecting position is assumed to be temporary elastic deformation of at least one of the parts (here preferably the cover). The locking seat can optionally be combined with the above-described clamping seat, so that a positive and non-positive connection between the parts is formed.

The cover may further comprise projections for engaging behind a fastener, so that it can be positively connected thereto. The projections are preferably formed as opposed folds of the (flat) material of the cover.

Furthermore, the cover may optionally have means for fixing to a wooden construction, in particular in the form of drivable in the wood, pointed in the front area projections.

According to one embodiment of the invention, the cover consists of at least two components that are complementary to a closed mold complement and then enclose the fastener in use. By such enclosing a fixation of the cover to the fastener and the associated timber construction is achieved simultaneously (with or without a clamping fit). The components may be separate and connectable for use, or they may be connected together and movable together. Furthermore, the components may optionally be L-shaped, U-shaped and / or in the form of half-shells.

According to a first variant of the preceding embodiment, the at least two components are separate from each other and have cooperatively formed hook elements at their abutting in use state abutting edges, by means of which the parts can be connected together.

According to another variant of the multi-component cover, the components are connected to each other via joints and / or Biegelini and have means for mutual attachment of the abutting edges on each other. Such a cover can be placed, for example, like a sleeve around a rod-shaped fastening device.

The multi-component covers also preferably have sections which overlap in use and thereby cover butt joints.

The various embodiments of the cover described above are preferably made of a flat material such as a sheet having a thickness of 0.5 to 1.5 mm, preferably 0.75 mm in thickness, since this is possible in cost punch-bending method. Suitable materials are metals, in particular galvanized iron, stainless steel, copper or aluminum, furthermore plastics or wood in question. Furthermore, the visible surfaces of the cover can be treated, for example by painting, coating (in particular powder coating), laminating, brushing, Matting, embossing or the like. In this way, virtually any desired aesthetic design of the covers can be achieved.

The outer, visible shape of the covers can be made substantially free according to the aesthetic requirements. In particular, it may consist of contiguous flat surface pieces and / or of curved surfaces or have these.

The invention further relates to the fastening system for a wooden structure, which contains the following components:

A fastener for the timber construction, such as a pole support or a ground socket.

A cover.

The cover and / or the fastening element in this case have means for mutual fixing to each other, and the cover conceals in use substantially all visible surfaces of the fastener.

The cover may be formed in particular in the manner explained above, d. H. in turn, have the means for fixing to the fastener and / or the associated wooden structure. Additionally or alternatively, however, such means may also be present on the fastening element.

13 shows a fifth, two-component embodiment of a cover 500;

14 shows a sixth, sleeve-like embodiment of a cover 600. In Figure 1, a post support 10 is shown made of galvanized steel, which has a flat bottom tab for attachment to a (hard) ground and two U-shaped thereof projecting upwardly leg 1 1. Between these legs 1 1, a wooden structure in the form of a wooden beam 1 can be used and secured by screws 12, which extend from one leg 1 1 to the opposite leg.

A problem with such mounting systems for posts and the like is that the attached to the beam 1 parts of the post carrier 10 are visible in an aesthetically unfavorable manner. Furthermore, the above screws and sharp edges represent a significant risk of injury.

To remedy this situation, covers 100 are used in the present case, which can be clamped onto the upstanding tabs 1 1 of the post carrier 10 to cover all visible and possibly interfering surfaces or projections. The outer surface of these covers 100 can be designed as desired according to the aesthetic specifications, for example by painting, brushing, matting or the like.

FIG. 1 also shows two covers 100 'for the bottom flaps of the post carrier 10. These are constructed analogously to the covers 100 except for dimensional adjustments and can optionally be used additionally or alternatively to these.

In Figure 2, the embodiment of the cover 100 is shown in more detail. The cover 100 consists of a large rectangular base surface 101 of the width b, at the longitudinal sides of which ei NEM angle side surfaces 103 connect. At the upper end in the figure, the surface 101 is adjoined by an end face 102 inclined at typically 30 ° -60 °, the inclination of which ensures a ramp-shaped connection of the cover 100 to the wooden beam 1 (FIG. 1). The end face 102 is formed so wide that it covers the bevelled edges of the side surfaces 103 and protects against the entry of water. The side surfaces 103 are clamping surfaces, which can be clamped non-positively on the upstanding tabs 1 1 of the post carrier 10 (Figure 1). For this purpose, the entire side surfaces 103 at an angle α of typically 2 ° -5 ° relative to the surface normal of the base surface 101 is slightly inclined inwardly attached to the base surface 101 (Figure 3, 4). The under the inclination angle α to each other running surfaces 103 can thus be plugged after elastic expansion on a flat iron with the approximate width b (minus the thickness of the cover), where they are then fixed by clamping fit.

As can be seen from FIG. 2 and the associated section along the line III-III in FIG. 3, moreover, a strip section 104 is inclined or folded inwardly along the free edge of the side face 103 by a larger angle β> α. This portion 104 does not penetrate to the lower end of the cover 100, wherein in the embodiment of FIG. 2, an optional slot 105 separates the more inclined portion 104 from the residual strip 106 of the side surface 103. The side surfaces 103 are thus inclined differently inwardly along their edges, whereby a clamping fit preferably takes place on the more inclined section 104. This prevents the clamping seat from being reached only selectively at the lower edge of the cover, which would otherwise be the case frequently, since post supports are typically widened by bending areas, weld seams and the like in these zones.

FIG. 5 shows a perspective view of a second embodiment of a cover 200 before it is attached to an H-shaped post carrier 20. The cover 200 is initially configured in the same way as the cover 100 explained above, which need not be described in detail. In addition, however, the cover 200 on the outer edge of the side surfaces 203 on projections 207, which can be driven into the wooden beams 1 and thereby additionally anchor the cover 200 in the wood. In FIG. 6, a typical shape of a projection 207 is shown enlarged. The following to a tip 207a, the same width trunk 207b of the projection 207 ensures a firm seat in the wood. While the covers 100, 100 ', 200 of Figures 1 to 6 are assembled outwardly from flat surface pieces, Figure 7 shows a third embodiment of a cover 300, which consists of a (nearly) cylindrically curved base 301 and a curved above Surface 302 (in the form of a half spherical cap) consists. The attachment of this cover 300 can in principle be carried out in a similar manner as in the covers described above. In the detailed views of Figures 8 and 9, however, an alternative embodiment of the attachment can be seen, according to the aufeinanderzuweisend bent bent longitudinal edges 307 of the base surface 301 act as projections, which can engage behind the upstanding tab 1 1 of the post carrier 10 (Figure 7). The cover 300 can thereby be placed on the tab 11 from the side taking advantage of its elasticity, or it can be pushed (without deformation) from above. The positive engaging behind parts of a post carrier can of course be realized in the other illustrated embodiments of covers.

Figures 10 to 14 show various embodiments of covers which completely enclose a fastener and thereby - possibly with an additional clamping seat - reach their attachment. Such covers are preferably used for covering of ground sleeves, as they also have an all-round extending (rectangular or round) sleeve for receiving a post 1. In FIG. 10, a rectangular bottom sleeve 30 with a flat foot is shown in this respect. Alternatively, such ground sleeves may also have downwardly facing mandrels for screwing or hammering into the ground or for setting in concrete, but it does not depend on the design of this section for the present invention. If a support for the lower edge of the cover that is similar to the flat bottom of the bottom sleeve 30 is missing (eg, with bottom sleeves with screw-in spikes), the cover typically rests on the bottom sleeve with its upper inwardly angled edge.

The fourth embodiment of a cover 400 shown in FIG. 10 consists of two separate components 400a, 400b, which in the example shown in FIG Are essentially L-shaped. The upper edges of the parts 400a, 400b are in turn beveled at about 45 ° in order to achieve a ramp-shaped connection to the wooden beams 1. Instead of the illustrated double L-shape, any other complementary shape could be used, which can be assembled into a closed mold. For example, one of the parts could be designed as U, which can be closed by a sheet-like part. Of course, the parts can also be rounded or (half) cup-shaped to enclose round bottom sleeves.

Figures 1 1 and 12 show the two components of the cover 400 of Figure 10 in more detail. In this case, hook elements 407a, 407b attaching in particular to the base surfaces 401 in an L-shaped manner can be seen, which hook into one another when the parts 400a, 400b are plugged together in the direction of the arrows. In the lower part 400b, the upper end chamfers 402 are preferably extended in the side regions by tab pieces 403 through which the butt joints are overlapped.

While two L-shaped projections 407a, 407b per edge are shown in FIGS. 10-12, other numbers (in particular one or three) of such projections could also be provided.

Figure 13 shows a fifth embodiment of a (two-component) cover 500, which in principle is similar to the cover 400 of Figures 10-12. Unlike the latter, however, there are no hook projections, but tab portions 508, 509 fitting perpendicularly to the side surfaces 501 of the (identically formed) cover portions 500a, 500b. The two portions of the cover 500 can be fixed to a post by the tabs 508, 509 from one of the parts (eg 500a) rest on the outer surfaces of the other part (500b) and thus hold the latter in the manner of a pincer.

FIG. 14 shows a sixth embodiment of a cover 600 which, like the covers 400 and 500 of FIGS. 10-13, can enclose a fastening element. In contrast to the above embodiments are at the cover 600, however, the two components 600a, 600b formed contiguous. The first component 600a is U-shaped and connected via a bending line 604 with the tabular second component 600b. At the end of the tabular component 600b there are tabs 605 which project at right angles and which can be inserted into corresponding slots of a tab 606 on the first component 600a and lock there.
